TraceTogether supports Singapore’s efforts to fight the spread of COVID-19 through community-driven contact tracing.

TraceTogether notifies you quickly if you’ve been exposed to COVID-19 through close contact with other TraceTogether users. The app allows the Ministry of Health (MOH) to give you timely care and guidance, protecting you and those around you.

The app uses Bluetooth, and your Bluetooth data is stored securely on your phone. It’ll only be shared with MOH if you test positive for COVID-19, for the sole purpose of contact tracing. Also, all Bluetooth data stored on your phone is automatically deleted after 25 days.

TraceTogether helps us ensure that we don’t spread the virus to our loved ones unknowingly. It also helps us support the work of contact tracers and healthcare workers by combating the spread of COVID-19 together.

App functionality will cease once the outbreak ends.

TraceTogether is designed for use by people in Singapore. To register, you will need a valid NRIC, FIN, or a valid document of your current stay in Singapore.

What’s New

Version 2.1.1

What's new:
- TraceTogether now works in the background on iOS — you don’t have to keep the app on the screen all the time anymore! For the app to work properly, turn on Bluetooth and keep the app open in the background. Do not swipe up on the app to close it.
- Quick check-ins and check-outs with SafeEntry QR

Version 2.1.1 fixes a bug in version 2.1 with devices that are iPhone 5 or older. We're sorry for the inconvenience. Take care and stay safe, everyone!

Check in/out a good feature

Great that I can check in and out with the App but would be great if I can get an overview of all the check-in’s so that I know exactly from where I need to check-out. A typical mall trip can easily clock 10+ check-in’s...

Finally Working in the Background

Thank you developers! Finally, something that would be useful and easy to use at the same time. The check in feature via Safe Entry is also a very convenient and helpful addition.

Now, I think one addition I am requesting that could be much much more useful: is there a way to have an apple watch app as well? That would be extremely useful! Although I am not sure if that is even possible.

Anyway, thank you!

Hello allan ray, thank you for your feedback. Without your participation, community-driven contact tracing would not be possible! Due to battery limitations of the Apple Watch, we don't think a TraceTogether Apple Watch app would be valuable to users.
